Access IText object with BarsAgo

[td_910]

HI,

With this code I can change the text color of the object I just created.

IText SpikeLong;
SpikeLong = DrawText("SpikeL"+(CurrentBar-1), true, "S"+SCBull.ToString(), 1, High[1]+2*TickSize, 0, Color.Black, new Font ("Arial", 8), StringAlignment.Center, Color.Empty, Color.Empty, 0);
 SpikeLong.TextColor = Color.Gray;

But how e.g can I access the object one bar ago?

What is the syntax to do this?

Thanks

Thomas

Hello td_910,
You can retrive the specific draw object from the DrawObjects collection. Please refer to the below code which further demonstrates it.

IText txt = (IText)DrawObjects["SpikeL" + (CurrentBar-2).ToString()];
if (txt != null)
{
	//do something
}

Very nice, Joydeep,

now I know how to access object properties of earlier created objects.

This works as well:

IText SpikeLong = (IText)DrawObjects["SpikeL" + (CurrentBar-2)];

But, just for curiosity, what do I use BarsAgo for?

Thanks

Hello td_910,
Glad to know it works fine for you.

The barsAgo property lets you to set where you want the text to be drawn (on the X/time axis)

The bar (x axis co-ordinate) where the draw object will be drawn. For example, a value of 10 would paint the draw object 10 bars back.

Yes, right, know that.
But what do I use it for when doing references with IText?

Hello td_910,
The DrawObjects collection will return the draw objects based on the name/tag of the draw object and not by the barsAgo property.
